Description

Technical Field

[0001] This utility model relates to the field of TPU multifilament wire harness technology, and in particular to a TPU multifilament wire harness cooling water tank. Background Technology

[0002] TPU multifilament harnesses (SGG), as a high-performance FDY product composed of 3 to 9 monofilaments, owe their excellent softness, elasticity, and high-temperature setting and bonding properties largely to the quality of the post-extrusion cooling and setting process. In this process, the performance of the cooling water tank is crucial.

[0003] Currently, conventional cooling water tanks in the industry typically employ a fixed guide roller structure. Molten TPU filaments are extruded from the die orifice, guided into the water tank by the inlet guide roller, and then exited by the outlet guide roller. This fixed structure has significant drawbacks: the spacing and position of the guide rollers are not adjustable, resulting in a fixed cooling path length for the filaments in the water. This makes it impossible to flexibly adjust the cooling time according to different linear densities and production speeds, affecting the crystallinity and performance stability of the product. Therefore, a TPU multi-filament filament cooling water tank is proposed. Utility Model Content

[0004] Therefore, it is necessary to address the aforementioned technical problems by providing a TPU multi-filament harness cooling water tank. By incorporating a horizontally movable second guide structure driven by a horizontal adjustment unit, this invention can adjust the required cooling path length of the filaments within the water tank. This not only means that cooling time can be flexibly controlled according to process requirements, ensuring better cooling and shaping effects for TPU filaments of different specifications, but also that the overall tension of the filaments can be fine-tuned by changing the path length, meeting the tension requirements of different applications and improving the equipment's process adaptability and product stability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A TPU multifilament harness cooling water tank includes a cooling water tank body, the cooling water tank body having a water tank for carrying cooling water inside, a first guide structure on both sides inside the water tank, a second guide structure inside the water tank near the first guide structure, and a third guide structure located between the two second guide structures.

[0007] The first guide structure is fixedly connected to the cooling water tank body via a support frame. Guide plates are fixed on both sides of the top of the cooling water tank body. A sliding gap is formed between the inner side of the guide plate and the cooling water tank body. A sliding frame is fixed on the surface of the second guide structure. The sliding frame is slidably assembled with the cooling water tank body through the sliding gap. A horizontal adjustment unit for driving the sliding frame is provided at the bottom of the cooling water tank body.

[0008] The surface of the third guide structure is equipped with a reciprocating moving unit and is assembled with the guide plate. The third guide structure can slide in the water tank under the action of the reciprocating moving unit.

[0009] The first guide structure, the second guide structure, and the third guide structure have the same structure;

[0010] The third guide structure includes a U-shaped frame, with a lower guide roller movably mounted on the bottom of the inner side of the U-shaped frame. Slide grooves are provided on both sides of the U-shaped frame, and an upper guide roller is slidably mounted in the slide grooves. Locking units are provided on both sides of the top of the upper guide roller.

[0011] Furthermore, both the lower guide roller and the upper guide roller have guide grooves on their surfaces that are compatible with the TPU wire harness, and correction rings are fixed on both sides of the guide grooves on the surfaces of the lower guide roller and the upper guide roller.

[0012] Furthermore, the locking unit includes a U-shaped rod, both ends of which pass through the groove and are fixed to the surface of the upper guide roller. The middle part of the U-shaped rod is movably connected to a movable handle via a bearing, and a locking block is fixed at the bottom end of the movable handle.

[0013] Furthermore, a through groove adapted to the locking block is provided on the top of the U-shaped frame, and a blind groove adapted to the locking block is also provided on the U-shaped frame, with the through groove and the blind groove set at a 90-degree angle.

[0014] Both sides inside the U-shaped frame are provided with springs that are sleeved on the surface of the U-shaped rod. One end of the spring is fixed to the surface of the U-shaped rod and the other end is fixed to the side wall of the U-shaped frame.

[0015] Furthermore, the leveling unit includes an adjusting motor fixed to the bottom wall of the cooling water tank, the output shaft of the adjusting motor is connected to a lead screw, the lead screw is threadedly engaged with the sliding frame, and the end of the lead screw is movably connected to a support block fixed to the cooling water tank via a bearing.

[0016] Furthermore, the reciprocating moving unit includes a support base fixed to the top of the third guide structure. A dual-axis drive motor is fixedly connected to the top of the support base. Both output ends of the dual-axis drive motor extend into the interior of the guide plate and are connected to gears. The gears mesh with a toothed plate fixed to the inner side of the guide plate.

[0017] Furthermore, both sides of the support base extend into the sliding gap for sliding assembly.

[0018] Furthermore, one end of the cooling water tank is connected to the input water pump via a connecting pipe, allowing external water to be input into the cooling water tank. The other end of the cooling water tank is connected to the output water pump via a connecting pipe, allowing water from inside the cooling water tank to be input to the outside.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The TPU multi-filament harness cooling water tank provided by this invention, through the setting of a horizontally movable second guide structure driven by a horizontal adjustment unit, can adjust the required cooling path length of the filaments in the water tank. This not only means that the cooling time can be flexibly controlled according to process requirements, ensuring that TPU filaments of different specifications can achieve better cooling and shaping effects, but also that the overall tension of the filaments can be finely adjusted by changing the path length to meet the tension requirements of different applications, thereby improving the process adaptability of the equipment and the stability of the products.

[0021] By incorporating a reciprocating third guiding structure, the continuous reciprocating motion of the structure not only guides the filament bundle but also generates a dual positive effect: firstly, it actively and periodically "combs" the filament bundle, effectively separating individual filaments that are prone to close together in the molten state, fundamentally reducing the risk of multi-filament adhesion (filament tangling) and improving the independence and integrity of the multi-filament bundle structure; secondly, it agitates the cooling water, breaking the inherent temperature stratification in the static water tank, making the water temperature more uniform, and further improving the uniformity of the cooling effect.

[0022] The first, second, and third guiding structures all employ guide roller designs with multiple guide grooves and correction rings. The guide grooves ensure precise lateral spacing when multiple monofilaments run in parallel, while the correction rings effectively constrain the axial movement of the filament bundle, preventing it from sliding on the roller surface, jumping out of the guide grooves, or even tangling together, thus ensuring the continuity and stability of the production process.

[0023] Furthermore, the guide structure adopts a unique locking unit design, which can quickly unlock or lock the upper guide roller by rotating the movable handle, making it convenient for threading operations or replacing and cleaning the guide roller, greatly reducing the labor intensity of operators and improving the efficiency of equipment maintenance and production line changeover.

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0042] Example 1

[0043] Please refer to Figures 1-9 As shown, a TPU multifilament harness cooling water tank includes a cooling water tank body 1. The cooling water tank body 1 has a water tank 11 for carrying cooling water inside. A first guide structure 2 is provided on both sides inside the water tank 11. A second guide structure 3 is provided inside the water tank 11 near the first guide structure 2. A third guide structure 4 is also provided between the two second guide structures 3.

[0044] The first guide structure 2 is fixedly connected to the cooling water tank 1 via a support frame 21. Guide plates 12 are fixed on both sides of the top of the cooling water tank 1. A sliding gap 13 is formed between the inner side of the guide plate 12 and the cooling water tank 1. A sliding frame 31 is fixed on the surface of the second guide structure 3. The sliding frame 31 is slidably assembled with the cooling water tank 1 through the sliding gap 13. A horizontal adjustment unit 5 for driving the sliding frame 31 is provided at the bottom of the cooling water tank 1.

[0045] The surface of the third guide structure 4 is equipped with a reciprocating moving unit 6, which is assembled with the guide plate 12. The third guide structure 4 can slide within the water tank 11 under the action of the reciprocating moving unit 6.

[0046] The first guide structure 2, the second guide structure 3, and the third guide structure 4 have the same structure.

[0047] One end of the cooling water tank 1 is connected to the input water pump 14 through a connecting pipe, so that the external water source is input into the cooling water tank 1. The other end of the cooling water tank 1 is connected to the output water pump 15 through a connecting pipe, so that the water source inside the cooling water tank 1 is input to the outside.

[0048] In practical applications, by starting the input water pump 14 and the output water pump 15, the constant temperature cooling water is circulated in the water tank 11. The input water pump 14 is used to input external cooling water into the water tank 11, and the output water pump 15 is used to output the water after heat exchange in the water tank 11 to the outside for unified collection, thus realizing the cooling of the TPU multi-filament bundle.

[0049] In this embodiment, the first guide structure 2 is used to guide the wire harness towards the inside of the water tank 11 and out of the water tank 11, while the second guide structure 3 is used to stabilize the wire harness inside the water body for cooling, and the third guide structure 4 can promote the active separation between multiple wire harnesses, while stirring the water flow to make the water body cool and hot evenly, thus achieving a better cooling effect.

[0050] Example 2

[0051] The TPU multi-filament wire harness cooling water tank provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the third guide structure 4 includes a U-shaped frame 41. A lower guide roller 42 is movably mounted on the bottom of the inner side of the U-shaped frame 41. The lower guide roller 42 can rotate inside the U-shaped frame 41 without shaking. The lower guide roller 42 can rotate freely. Slide grooves 47 are provided on both sides of the U-shaped frame 41. An upper guide roller 43 is slidably mounted in the slide grooves 47. The upper guide roller 43 can slide along the height direction of the U-shaped frame 41 through the action of the slide grooves 47. Locking units 44 are provided on both sides of the top of the upper guide roller 43.

[0052] The surfaces of the lower guide roller 42 and the upper guide roller 43 are both provided with guide grooves 45 that are adapted to the TPU wire harness. On both sides of the guide grooves 45, the surfaces of the lower guide roller 42 and the upper guide roller 43 are fixed with correction rings 46. Under the constraint of the correction rings 46, the wire harness is precisely restricted to run stably within the guide grooves 45, completing the uniform and controllable cooling and shaping from the molten state to the solid state, laying a solid foundation for the subsequent preparation of high-performance TPU multi-filament wire harness products.

[0053] Furthermore, the locking unit 44 includes a U-shaped rod 440, both ends of which pass through the slide groove 47 and are fixed to the surface of the upper guide roller 43. The middle part of the U-shaped rod 440 is movably connected to a movable handle 441 through a bearing. The movable handle 441 can rotate horizontally on the surface of the U-shaped rod 440 without sliding up and down. A locking block 442 is fixed at the bottom end of the movable handle 441.

[0054] The top of the U-shaped frame 41 is provided with a through groove 443 that is adapted to the locking block 442. The U-shaped frame 41 is also provided with a blind groove 444 that is adapted to the locking block 442. The through groove 443 and the blind groove 444 are set at a 90-degree angle.

[0055] Both sides of the U-shaped frame 41 are provided with springs 445 sleeved on the surface of the U-shaped rod 440. One end of the spring 445 is fixed to the surface of the U-shaped rod 440 and the other end is fixed to the inner wall of the U-shaped frame 41. Under the action of the spring 445, the upper guide roller 43 is in contact with the surface of the lower guide roller 42 in a natural state.

[0056] The operator pulls the movable handle 441, causing it to move upward against the force of the spring 445. This upward movement raises the locking block 442 above the through groove 443. The operator then rotates the movable handle 441, aligning the locking block 442 with the blind groove 444, thus locking the locking block 442 into the blind groove 444. This allows the molten TPU multifilament bundle from the mold opening to sequentially pass through the guide grooves 45 of the first guide structure 2, the second guide structure 3, and the third guide structure 4, finally leading to the traction device. Afterward, rotating the movable handle 441, through the force of the spring 445, resets the upper guide roller 43, pressing the filament bundle firmly into the guide groove 45, completing the threading process.

[0057] Example 3

[0058] The TPU multi-filament wire harness cooling water tank provided in Embodiment 1 or 2 is further optimized, such as... Figure 2 As shown, the horizontal adjustment unit 5 includes an adjustment motor 51 fixed to the bottom wall of the cooling water tank 1. The output shaft of the adjustment motor 51 is connected to a lead screw 52. The lead screw 52 is threadedly engaged with the sliding frame 31. The end of the lead screw 52 is movably connected to a support block 53 fixed to the cooling water tank 1 via a bearing. The U-shaped frame in the second guide structure 3 is fixedly connected to the sliding frame 31. The sliding frame 31 can slide along the length direction of the cooling water tank 1 through the cooperation of the sliding gap 13.

[0059] Adjusting the cooling path and tension: Based on the current TPU filament specifications, such as the number of monofilaments, linear density, and spinning speed, start the adjusting motor 51 of the horizontal adjusting unit 5. The adjusting motor drives the lead screw 52 to rotate, which in turn drives the sliding frame 31 of the second guide structure 3 to move horizontally along the sliding gap 13, thereby changing the distance between the second guide structure 3 and the first guide structure 2.

[0060] Example 4

[0061] The TPU multi-filament harness cooling water tank provided in Example 3 has been further optimized, such as... Figure 9 As shown, the reciprocating moving unit 6 includes a support base 64 fixed to the top of the third guide structure 4. The support base 64 is fixed to the top of the U-shaped frame inside the third guide structure 4 and will not affect the lifting of the movable handle on it. A dual-axis drive motor 61 is fixedly connected to the top of the support base 64. Both output ends of the dual-axis drive motor 61 extend into the interior of the guide plate 12 and are connected to gears 62. The output ends of the dual-axis drive motor 61 are movably connected to a shaft seat and fixed to the support base 64, which can improve the driving stability in the rotation state of the output end. The gears 62 mesh with the toothed plate 63 fixed inside the guide plate 12.

[0062] Both sides of the support base 64 extend into the sliding gap 13 for sliding assembly, thus ensuring the stability of the third guide structure 4 during sliding. During the cooling process, the dual-axis drive motor 61 of the reciprocating unit 6 can be activated. The motor drives the gear 62 to roll along the toothed plate 63, thereby driving the entire third guide structure 4 to slide smoothly and reciprocally in the horizontal direction within the water tank.

[0063] In the sliding state, the reciprocating motion of the third guide structure 4 causes the guided filament bundle to be periodically pulled laterally in small amplitudes, producing a "combing" effect on the still molten monofilaments, forcibly separating monofilaments that may be close together, and reducing the occurrence of filament tangling. Moreover, the movement of the third guide structure 4 acts like a stirrer, breaking the static state of the water, making the heat distribution more uniform, avoiding local overheating or undercooling, and ensuring the consistency of filament bundle quality.
